HEAD-REST AND CONTROL 2 Sheets-Sheet 2 Filed Dec. 8, 195a Aunt LV- United States Patent 2,989,341 HEAD-REST AND CONTROL Fridtjof F. Schliephacke, Hundekehlenstrasse 18, Berlin- Schmargendorf, Germany, assignor to Anton Lorenz, Boynton Beach, Fla.

Filed Dec. 8, 1958, Ser. No. 778,819 11 Claims. (Cl. 155-177) The present invention relates generally to an improved reclining chair, and in particular to a head-rest and control arrangement for such reclining chair wherein the head-rest is automatically displaced to an extended headsupporting position relative to the back-rest in response to reclining movement of the chair.

It is generally known to construct a reclining chair which includes a support and body-supporting means having a back-rest movably mounted on the support such that the back-rest may be moved into various reclined positions under the control of the chair occupant. Such reclining chairs may incorporate a head-rest positioned adjacent the upper end of the back-rest, and preferably stored within the outline of the back-rest such that the head-rest may be extended or elevated relative to the backrest to provide a more comfortable and adequate support for the head of the chair occupant. With such an extensible head-rest, the back-rest may be made somewhat shorter for esthetic and designed reasons, yet the chair occupant may be comfortably accommodated when in the various reclining positions by the additional support of the head-rest.

Broadly, it is an object of the present invention to provide an improved head-rest and control arrangement for a reclining chair wherein the head-rest is automatically extended as a function of the reclining movement of the back-rest of the chair.

Of recent times there has been developed a doublemovement recliner type of reclining chair which includes a movable back-rest, seat and leg-rest and a coordinating linkage arranged such that during a first phase of the reclining movement the seat and back-rest are moved to an intermediate tilted or semi-reclined position, with substantially no angular change between the seat and back-rest; and during a second phase of the reclining movement the seat and back-rest are moved into various reclined positions, with a progressive increase in the included angle between the seat and back-rest. The legrest is operated to move to its elevated leg-supporting position in response to the first phase of the reclining movement such that the leg-rest is in its proper position to support the legs of the chair occupant throughout the second phase of the reclining movement. For such double-movement chair, and for rester type multiple-position chairs having a unitary seat and back-rest, the head-rest and its control arrangement should be designed to bring the head-rest into the extended head-supporting position during the first phase of the reclining movement such that the head-rest is positioned to support the head of the chair occupant at the end of the first phase of the reclining movement and when the chair is in the semi-reclined or intermediate tilted position appropriate for television viewing, reading or the like. Further, the head-rest should remain substantially stationary and in the extended headsupporting position during the second phase of the reclining movement such that the chair occupant does not experience a change of support at the back of the head which would occur if there were relative movement between the head-rest and the back-rest during the second motion phase.

It is a further object of the present invention to provide a head-rest and control suitable for use in a doublemovement type of reclining chair. Specifically, it is with in the contemplation of the present invention to provide 'ice 2 i an improved head-rest and control which is effective in response to the first phase or portion of the reclining movement of a chair to translate the head-rest from its stored position to its extended position to thereby provide an adequate support for the head of the chair occupant, with the head-rest remaining in the extended position during a second phase or further portion of the reclining movement of the chair. a

In accordance with an illustrative embodiment demonstrating features and advantages of the present invention there is provided a reclining chair of the doublemovement type which includes a support and aback-rest and seat mounted on the support for inclining and reclining movement respectively through first and second motion phases, a head-rest, and means mounting-the head rest for movement from a stored position relative to the back-rest to an extended head-supporting position relative thereto. Actuating means are operatively connected to the head-rest for moving the head-rest to the extended position during the first motion phase and for maintaining the head-rest in the extended position during the second motion phase, with the actuating means including an ad tuating member operatively connected to the mounting member for the head-rest and pivotally mounted on the back-rest at the pivotal mount which moves relative lo the support in response to its reclining movement of the chair. Constraining means are operatively connected to the support and have a pivotal connection to the actuating member guided to move relative to the pivotal mount during the first motion phase to impart a turning movement to the actuating member which is effective to move the head-rest to the extended head-supporting position. The constraining means is arranged such that there is no turning movement of the actuating member during the second motion phase whereby the head-rest remains in the extended head-supporting position. Although the instant head-rest is primarily intended to be employed in. a chair of the double-movement type, as the description proceeds it will become apparent that the control is also suitable for the usual reclining chair of the recliner or rester type wherein it may be desirable to provide for the automatic extension of the head-rest and for rester type multipleposition chairs having a unitary seat and back-rest.

The above brief description, as well as further objects, features, and advantages of the present invention will be more fully appreciated by reference to the following detailed description of several illustrative embodiments according to the present invention, when taken in conjunction with the accompanying drawing wherein: 7

FIG. 1 is an elevational view, with parts brokenaway for clarity, of a portion of a reclining chair of the doublemovement type incorporating my improved head-rest and control arrangement shown in the upright or sitting position; 1

FIG. 2 is an elevational view similar to FIG..1, showing the reclining chair at the end of the first motion phase and in the intermediate tilted or semi-reclined position,

with the head-rest in the extended head-supporting position;

FIG. 3 is an elevational view showing the reclining chair in the fully reclined position at the end of the secwith the head-rest in the extended head-supporting position; and

FIG. 6 is .an elevational view similar to FIG. 5, but showing the'reclining chair in' the fully-reclined position at the end of the second motion phase, with the head-rest remalning in the extended head-supporting position. Referring now specifically to FIGS. 1 to 3 of the drawrugs, there is partially shown a reclining chair, of general: ly known construction and designated by the reference numeral 10, which incorporates my improved head-rest and control arrangement. For a detailed description of the construction of the reclining chair 10, reference may be' made to my copending application Serial No. 760,334, filed September 11, 1958, and entitled Reclining Chair and Leg-Rest Control. Inthe interest of simplicity and clarity the instant description will deal with the head-rest and control arrangement, with only brief reference being made to the remaining construction of the chair. Generally, the chair 10 incorporates a support 12 upon which is movably mounted a body-supporting unit including a movable back-rest 14 and a movable seat 16. The back-rest 14 is" pivoted adjacent its lower end on the chair frame 12 at a back-rest pivot 18. The seat 16 carries rearwardly directed rigid hangers 20 which provide a seat pivot 22 on the back-rest 14 at a point spaced above the back-rest pivot 18 and in position to move through a rearward and downward are about the back-rest pivot 18. Operative- 1y connected to the back-rest 14 at the pivot 24 is a corinecti'ng link 26 which inclines the seat 16 and elevates the'leg-rest, as detailed in said copending application.

. The 'coordination of the components of the illustrative double-movement chair which is subject to a latitude of variation and change is substantially as follows:

When the chair occupant is seated therein and leans ag inst the back-rest 14, the back-rest turns about the hack-rest pivot 18 and a rearward pull is imparted to the connecting link 26 which inclines the seat 16 and elevates the leg-rest such thatthe reclining chair may be initially moved from the normal sitting position as illustrated in FIG. 1 to an intermediate tilted or semi-reclined position as illustrated in FIG. 2 wherein there is substantially no change in the angle between the back-rest 14 and .the seat 16 which are tilted back as a unit, with the leg- :rest moving to an elevated leg-supporting position. Forther in response to continued rearward reclining movement of the backrest, the chair may be moved from the intermediate tilted or semi-reclined position of FIG. 2 ,to the fully-reclined position illustrated in FIG. 3 wherein .the anglejbetween seat and back-rest increases, with the leg-rest remaining in the elevated leg-supporting position.

In accordance with the present invention, a head-rest 30 is disposed in a stored or retracted position between the opposite sides 14a, 14b of the back-rest 14 intermediate the forward and rearward cross-braces 14c, 14d.

JThe head-rest 30 is disposed with its upper face substantiallycoplanar or coextensive with the upper face of the back-rest, with the head-rest bridging the slot or opening formed in the back-rest 14 and bounded by the opposite sides 14a, 14b and cross-braces 14c, 14d thereof. The head-rest 30 is mounted for extensile and retractile' movement by a mounting member or link 32 which extends substantially lengthwise of the back-rest 14 and has its upper end rigidly connected to the head-rest 30.

Guide means are operatively connected between the mounting member or link 32 and the back-rest 14 such that the head-rest 30 moves along a generally upward path from the retracted or stored position illustrated in FIG. 1 to the extended head-supporting position illustrated in FIGS. 2 and 3. In this embodiment the guide means includes a guide plate 34 having an elongated guide slot 34a formed therein, which guide plate is fixed to the adjacent side of the back-rest 14, with a pin 36 being carried'by the mounting member 32 and guidingly engaged within the slot 34a. The pin and slot guiding means is arranged such that the pin 36 is at the lowermost end of slot 34a to establish the stored or retracted position for the head-rest 30, with its upper face substantially coplanar with the upper face of the back-rest 14. The slot 34a extends substantially lengthwise and upwardly relative to the back-rest and is of a length and contour to guide the head-rest 30 upwardly and forwardly to the head-supporting position illustrated in FIGS. 2 and 3 wherein the front or supporting surface of the head-rest 30 is properly oriented relative to the front or supporting surface of the back-rest 14 to serve the head-supporting function.

A combined guiding and actuating linkage is operatively connected to the chair frame or support 12, to the back-rest 14, and to the mounting member 32 and cooperates with the pin and slot interconnection 34, 36 to guide the head-rest 30 to move along a prescribed course and is operative to displace the head-rest 30 from the stored or retracted position to the extended headsupporting position in response to the first phase of reclining movement. The combined guiding and actuating linkage includes an actuating member 38 in the form of a double-arm actuating lever pivotally mounted intermediate its end on the back-rest 14 at a pivotal mount 40 such that the pivotal mount moves in a prescribed arcuate path about the back-rest pivot 18 in response to reclining movement. The downwardly and rearwardly extending arm 38a of the double-arm actuating lever 38 (see FIG. 1) has a pivotal connection 42 to the lower end of the mounting member 32 such that turning movement of the actuating lever 38 about its pivotal mount 40 on the back-rest 14 in the counter-clockwise direction moves the head-rest from the retracted position (see FIG. 1) to the extended head-supporting position (see FIGS. 2 and 3). Means are operatively connected to the other arm 38b of the actuating lever 38 and to the support or chair frame 12 which are effective to guide a portion of the arm 38b along a prescribed path or course such that the requisite counterclockwise turning movement is imparted to the arm 38a of the actuating lever 38 to move the head'rest 30 to the extended position during the first phase of the reclining movement. In this embodiment the arm 38b is formed with a guideway 44 having an upwardly extending linear section 44a and a forwardly extending arcuate section 44b. Engaged within the guideway 44 is a stationary pivot 46 which is secured to the chair frame or support 12. The guideway 44 and the pivot 46 constrain the arm 38b of the lever 38 to move in a path relative to the pivotal mount 40 suchthat conjoint effect of the movement of the pivotal mount 40 on the back-rest 14 and of the constraint on the arm 38b to the support is to turn the arm 38a through an upward are which is effective to impart an upward thrust to the mounting member 32 to displace the headrest 30 into the extended head-supporting position. Specifically, in response to the reclining movement of the back-rest 14 about the back-rest pivot 18, the pivotal mount 40 moves through an upward and rearwardly directed arc, as may be appreciated by progressively inspecting FIGS. 1 and 2, with the pivotal mount 40 moving away from the stationary pivot 46. Simultaneously, the

stationary pivot 46 coacts with the linear or straight section 44a of the guideway 44 to guide the arm 38b genor intermediate tilted position illustrated in FIG. 2

wherein the head-rest 30 is fully extended. The guideway section 4412 is of a curvature on a radius about the back-rest pivot 18 (see 'FIG. 2) such that during the second phase of the reclining movement there is a lost motion travel of the guideway section 44b relative to the stationary pivot 46, with no turning movement being imparted to the actuating lever 38 during the translation of the guideway section 44b upwardly and rearwardly relative to the stationary pivot '46. The guideway section 44b allows the back-rest and head-rest to move rearwardly as a unit, with no relative displacement between the back-rest and head-rest from the semi-reclined or intermediate tilted position of FIG. 2 to the fully reclined position of FIG. 3 such that the requisite increase in the angular relationship between the back-rest 14 and seat 16 may be achieved without changing the relative position of the headrest 30 to the back-rest 14. When the stationary pivot 46 is contacted by the forward extremity of the guideway section 44b, the head-rest control linkage establishes the end of the second motion phase of the chair, with the requisite angular relationship between the back-rest 14 and the seat 16 and with the headrest 30 remaining in the extended head-supporting position.

A typical sequence of operations will now be described in detail to facilitate a more thorough understanding of the present invention:

When the chair occupant is seated in the reclining chair and leans against the back-rest 14, the back-rest moves rearwardly, turning about the back-rest pivot 18 and displacing the pivotal mount 40 for the actuating member 38 through an upwardly and rearwardly directed arc away from the stationary pivot 46. The conjoint effect of the movement of the pivotal mount 40, the guiding action of the pin and slot guiding means 34, 36, and the guiding action of the pin and slot guiding means 44, 46 is to cause the head-rest 30 to move'to the extended headsupporting position. During such movement the headrest 30 is accurately guided in its translation relative to the back-rest :14 in accordance with the dimensioning and geometry of the linkages and the respective guiding slots. At the time when the actuating lever 38 is displaced to a position wherein the stationary pivot 46 is at the juncture of the guideway sections 44a, 44b, the first phase of the movement of the reclining chair is terminated with the back-rest 14 and seat 16 displaced to a rearwardly tilted position and with the head-rest 30 extended. As detailed in the mentioned copending application, the leg-rest is moved to the elevated leg-supporting position in response to such first phase of the reclining movement incident to the rearwardly directed pull on the connecting link 26. When the chair occupant leans further against the back-rest 14, the back-rest continues to turn about the back-rest pivot 18. During such second phase of the reclining movement, the actuating lever '38 is moved rearwardly with the back-rest 14 but there is no turning force imparted. thereto due to the design of the guideway section 44b which allows for the lost motion travel of the backrest 14 and head-rest 30 as a unit, with the head-rest remaining substantially stationary and in the extended head-supporting position. When the forward extremity of the guideway section 44b contacts the stationary pivot 46, the end of the second motion phase is established and the several components of the reclining chair are oriented relative to each other to accommodate the chair 0ccupant in a complete relaxation position. When the chair occupant desires to restore the chair to the intermediate tilted position illustrated in FIG. 2 and then to the up right sitting position of FIG. 1, the occupant merely exerts a downward pressure against the leg-rest which causes the chair to move in the reversed direction through its motion phases. 7

Referring now specifically to FIGS. 4 to 6 of the drawings, there is partially shown a further reclining chair of generally known construction and designated by the reference numeral 110, which incorporates a further headrest and control arrangement constructed in accordance with the present invention. The chair 110 incorporates a support 112 upon which is movably mounted a bodysupporting unit including a back-rest 114 and a seat 116. The rack-rest 114 is pivoted adjacent its lower end on the chair frame 112 at a back-rest pivot 118. The seat 116 carries rearwardly directed. rigid hangers 120, which via a' 'mount ing fixture plate 121 provides a seat pivot 122 oufthe back-rest 114 at a point spaced above .thebacka rest pivot 118 and in position to move through a rearward and downward arc about the back-rest pivot 118. Operatively connected to the back-rest 114 via the fixture plate 121 at the pivot 124 is a connecting'link 126 which inclines the seat 116 and elevates the leg-rest as detailed in said copending application.

In accordance with this embodiment of the present invention, a head-rest 130 is disposedin a stored. or retracted position between the opposite sides 114a, 114b of the back-rest 114 intermediate the forward and rearward cross-braces 1140, 114d. The head-rest 130 is disposed with its upper face substantially coplanar or coextensive with the upper face of the back-rest 114 and bridging the slot or opening bounded by the opposite sides 114a, 114k and cross-braces 1141:, 114d thereof. The head-rest is mounted for extensile and retractile movement by a mounting member or link 132 which extends substantially lengthwise of the back-rest 114 and has its upper end rigidly connected to the head-rest 130.

I Guide means are Operatively connected between the mounting member or link 132 and the back-rest 114.such that the head-rest 130 moves along a generally upward path from the retracted orstored position illustrated in FIG. 4 to the extended head-supporting position illus trated in FIGS. Sand 6. In this embodiment the guide means includes a guide link 134 having a pivotal connection 135 at one end to the back-rest 114 and a pivotal connection 136 at the other end to the mounting member 132. The guide link 134 is disposed in a downwardly inclined position (see FIG. 4) to establish the stored or retracted position for the head-rest 130 with its upper face coplanar with the upper face of the back-rest 114. The guide link 134 swings upwardly relative to the backrest 114 about the pivotal connection 135 to guide the head-rest 130 upwardly and forwardly into the head: supporting position illustrated in FIGS. 5 and 6 wherein the front or supporting surface of the head-rest is properly oriented relative to the front or supporting surface of the back-rest to serve the head-supporting function.

A combined guiding and actuating linkage is operatively connected to the chair frame or support 112, to the back-rest 114, and to the mounting member 132 and cooperates with the guiding link 134- to constrain the head-rest 130 to move along a prescribed course and is operative to displace the head-rest 130 from the stored or retracted position to the extended head-supporting position in response to the first phase of reclining movement. The combined guidingand actuating linkage includes an actuating member 138 in the form of a double-arm lever pivotally mounted intermediate its ends on the back-rest 114 at a pivotal mount 140 such that the pivotal mount moves in a prescribed arcuate path about the back-rest pivot 118 in response to reclining movement. The downwardly and rearwardly extending arm 138a of the double arm actuating lever 138 (see FIG. 4) has a pivotal connection 142 to the lower end of the mounting member 132 such that turning movement of the actuating lever about its pivotal mount 140 on the back-rest 114 in the counter-clockwise direction moves the head-rest 130 from the retracted position (see FIG. 4) to the extended headsupporting position (see FIGS. 5 and 6). Means are Operatively connected to the other arm 138b of the actuating lever 138 and to the support or chair frame 112 which are effective to guide a portion of the arm 138b along a prescribed path or course such that the requisite counter-clockwise turning movement is imparted to the arm 138a of the double-arm lever 138 to move the headrest 130 to the extended position during the first phase of the reclining movement. In this embodiment the arm 13% is formed with an arcuate guideway 144. Guidingly engaged within the guideway 144 is a pivot 146 which is carried on a further guiding link having a pivotal mount 147 on the support. Stop means 149, 51

are fixed to the support 112 at opposite sides of the guiding link 145 to limit the swinging movement thereof. The guiding link 145' and pivotal connection 146 constrain the arm 138b of the lever 138 to move in a path relative to the pivotal mount 140 such that conjoint efiect of the movement of the pivotal mount 140 and of the constraint on the arm 13817 is to turn the arm 138a through an upward are which is eifective to impart an upward thrust to the mounting member 132to displace the head-rest 130 intothe extended head-supporting position. Specifically, in response to the reclining movement of the back-rest 114 about the back-rest pivot 118, the pivotal mount 140 moves through an upward and rearwardly directed are, as may be appreciated by progressively inspecting FIGS. 4 and 5. Simultaneously, link 145 rocks rearwardly from its limit position against the stop 149 to move the pivotal connection 146 through a rearward and downward arc to guide the arm 13% such that the requisite turning movement is imparted to the lever 138. The stop 151 is located such that the requisite extension is imparted to the head-rest 130 while the relationship is established between the back-rest 114 and the seat 116 which corresponds to the semi-reclined or intermediate tilted position illustrated in FIG. 5. The guideway 144 is of a curvature on a radius about the back-rest pivot 118 (see FIG. 5) such that during the second phase of the reclining movement there is a lost motion travel of the guideway 144 relative to the pivot 146 which remains stationary, with no turning movement being imparted to the actuating lever 138 during the translation of the guideway 144 upwardly and rearwardly relative to the pivot 146. The guideway 144- allows the back-rest and head-rest to move rearwardly as a unit, with no relative displacement between the back-rest and head-rest from the semi-reclined or intermediate tilted position of FIG. 5 to the fully reclined position of FIG. 6 such that the requisite increase in the angular relationship between the back-rest 114 and the seat 116 may be achieved withbut changing the relative position of the head-rest 130 in relation to the back-rest 114. When the pivot 146 is contacted by the forward extremity of the guideway 144, the head-rest control linkage establishes the end of the second motion phase of the chair, with the requisite angular relationship between the back-rest 114 and the seat 116 and with the head-rest 130 remaining in the extended headsupporting position.
